Plastic surgery statistics

Statistics say that any given year, 50 percent of plastic surgery patients are repeat patients. Assume this percentage has not changed through the years.

Given that and a random sample of people who have had plastic surgery, what percentage would you expect to have had more than one? 50, more than 50, less than 50, can not say? If more or less, is it a lot or a little more/less?

I thought the answer was 50. I thought of it as an entry/exit interview, wherein if 50 percent of people going in for a plastic surgery have not had it before, then 50 percent coming out have had it only once?

But then I thought, well, would the people who have had more than one surgery but not in the past year skewer the pools, and whether the pools of "people who have just had a surgery" and "people who ever had a surgery" would be any different for the purposes of this problem...

Can somebody help?
